The ratio of boys to girls in the Science Club is 3.5. If there are 60 girls, how many boys are there?
liubo4ka [24]

Answer:

36 boys

Step-by-step explanation:

                                                            3

Please write the ratio as 3:5 or as  --------

                                                             5

Note that 3 + 5 = 8, so that the fraction of boys in the club is 3/8 and that of girls is 5/8.  

How many are in the club altogether?  Let this count be represented by c.  Then (5/8)c = 60.

Multiplying both sides of this equation by (8/5), to isolate c, we get:

c = (8/5)(60) = 96.  Thus, there are 96 Science students altogether.

3/8 of this number are boys.  This comes out to (3/8)(96) = 36 boys.

We could also solve this problem in the following manner:

 3          b

------ = ------- , where b represents the number of boys.

  5        60

Then 5b = 180.  Dividing both sides by 5, we get b = 180/5 = 36 boys

Solve for x in the equation.
oksano4ka [1.4K]
x^2 + 20x + 100 = 36

(x + 10)^2 = 36

x + 10 = \pm \sqrt{36}

x + 10 = 6   or   x + 10 = -6

x = -4   or   = -16

Hello.

The answer is <em>D. It is reviewed and amended.  </em>The reason why is because the State Constitution(s) are usually longer than the regular Constitution, which has roughly 4,000 words. State Constitutions are normally 8,500 words or longer. So it takes a long time to amend because they are longer.

Margaret [11]

Answer:

177 girls

Step-by-step explanation:

3:4     = girls:boys        

3:4     =    ?:236

3        =     ?

4        =      236

236 divided by 4 equals 59.

Multiply the number of girls by 59 to get your answer.

3*59=177

3:4          =               177:236

girls:boys                 girls:boys
